摘要： In a multi-beam light source device of the invention, a light source unit holds light sources and coupling lenses, the coupling lenses coupling light beams emitted by the light sources. A base member holds the light source unit such that the light beams from the light source unit held by the base member are rotatable in a direction perpendicular to a main scanning direction of an optical scanning device. An angle adjustment mechanism is provided for adjusting a mounting angle of the light source unit relative to the base member, so that respective pitches of beam spots, formed on a scanned surface by the light beams, in the direction perpendicular to the main scanning direction are variable in accordance with the mounting angle adjustment.
